The present invention provides recombinant adenoviral vectors, immunogenic compositions thereof and their uses in medicine. In particular, the present invention provides an adenoviral vector comprising the genome of an adenovirus other than AdHu5 and AdY25, wherein the genome of the adenovirus has been modified such that the vector lacks the native E4 locus of the adenovirus and comprises heterologous E4Orf1, E4Orf2 and E4Orf3 coding regions from AdY25.

The invention relates to vectors comprising two or more homologous nucleotide sequences and methods for generating them. The invention concerns substituting bases in the homologous nucleotide sequences with different bases that do not alter the encoded amino acid sequence. The invention allows for the reduction of intramolecular recombination between homologous nucleotide sequences, in particular in mammalian cells. The invention further relates to nucleotide sequences containing substituted bases.

The present invention is directed to bispecific, heterodimeric checkpoint antibodies.

The invention provides compositions and formulations and use of these compositions and formulations to preserve viral vectors. In particular, the particular embodiments relate to compositions and formulations of trehalose or derivatives thereof as suitable protectants for long-term storage of viral vectors and for both in vitro and in vivo applications

The invention generally relates to compositions and methods for preventing and treating cancer. More specifically, the invention relates to antigenic polypeptides and their use in cancer vaccines that may be used, in part, to treat cancer types dependent upon HER2-mediated signaling.

The present invention relates to the field of (vector) vaccines, and especially to novel promoter sequences, expression cassettes and vectors, which are suitable to express genes of interest, especially antigen encoding sequences. The viral vectors of the present invention are useful for producing an immunogenic composition or vaccine.

Embodiments herein report compositions, uses and manufacturing of dengue virus constructs and live attenuated dengue viruses. Some embodiments concern a composition that includes, but is not limited to, a tetravalent dengue virus composition. In certain embodiments, compositions can include constructs of one or more serotypes of dengue virus, such as dengue-1 (DEN-1) virus, dengue-2 (DEN-2) virus, dengue-3 (DEN-3) or dengue-4 (DEN-4) virus constructs. In other embodiments, constructs disclosed herein can be combined in a composition to generate a vaccine against more one or more dengue virus constructs that may or may not be subsequently passaged in mammalian cells.
